Efficacy of Wolbachia-Infected Mosquito Deployments for the Control of Dengue.

BACKGROUND: Aedes aegypti mosquitoes infected with the wMel strain of Wolbachia pipientis are less susceptible than wild-type A. aegypti to dengue virus infection. METHODS: We conducted a cluster-randomized trial involving releases of wMel-infected A. aegypti mosquitoes for the control of dengue in Yogyakarta, Indonesia. We randomly assigned 12 geographic clusters to receive deployments of wMel-infected A. aegypti (intervention clusters) and 12 clusters to receive no deployments (control clusters). All clusters practiced local mosquito-control measures as usual. A test-negative design was used to assess the efficacy of the intervention. Patients with acute undifferentiated fever who presented to local primary care clinics and were 3 to 45 years of age were recruited. Laboratory testing was used to identify participants who had virologically confirmed dengue (VCD) and those who were test-negative controls. The primary end point was symptomatic VCD of any severity caused by any dengue virus serotype. RESULTS: After successful introgression of wMel into the intervention clusters, 8144 participants were enrolled; 3721 lived in intervention clusters, and 4423 lived in control clusters. In the intention-to-treat analysis, VCD occurred in 67 of 2905 participants (2.3%) in the intervention clusters and in 318 of 3401 (9.4%) in the control clusters (aggregate odds ratio for VCD, 0.23; 95% confidence interval [CI], 0.15 to 0.35; P = 0.004). The protective efficacy of the intervention was 77.1% (95% CI, 65.3 to 84.9) and was similar against the four dengue virus serotypes. The incidence of hospitalization for VCD was lower among participants who lived in intervention clusters (13 of 2905 participants [0.4%]) than among those who lived in control clusters (102 of 3401 [3.0%]) (protective efficacy, 86.2%; 95% CI, 66.2 to 94.3). CONCLUSIONS: Introgression of wMel into A. aegypti populations was effective in reducing the incidence of symptomatic dengue and resulted in fewer hospitalizations for dengue among the participants.

Spatial model of Dengue Hemorrhagic Fever (DHF) risk: scoping review.

BACKGROUND: Creating a spatial model of dengue fever risk is challenging duet to many interrelated factors that could affect dengue. Therefore, it is crucial to understand how these critical factors interact and to create reliable predictive models that can be used to mitigate and control the spread of dengue. METHODS: This scoping review aims to provide a comprehensive overview of the important predictors, and spatial modelling tools capable of producing Dengue Haemorrhagic Fever (DHF) risk maps. We conducted a methodical exploration utilizing diverse sources, i.e., PubMed, Scopus, Science Direct, and Google Scholar. The following data were extracted from articles published between January 2011 to August 2022: country, region, administrative level, type of scale, spatial model, dengue data use, and categories of predictors. Applying the eligibility criteria, 45 out of 1,349 articles were selected. RESULTS: A variety of models and techniques were used to identify DHF risk areas with an arrangement of various multiple-criteria decision-making, statistical, and machine learning technique. We found that there was no pattern of predictor use associated with particular approaches. Instead, a wide range of predictors was used to create the DHF risk maps. These predictors may include climatology factors (e.g., temperature, rainfall, humidity), epidemiological factors (population, demographics, socio-economic, previous DHF cases), environmental factors (land-use, elevation), and relevant factors. CONCLUSIONS: DHF risk spatial models are useful tools for detecting high-risk locations and driving proactive public health initiatives. Relying on geographical and environmental elements, these models ignored the impact of human behaviour and social dynamics. To improve the prediction accuracy, there is a need for a more comprehensive approach to understand DHF transmission dynamics.

"I would do something if I could!": experiences and reflections from ethics teachers on how to respond when hearing alarming cases from medical students.

BACKGROUND: Previous studies show that teachers can feel disturbed by alarming cases brought up by students during their teaching activities. Teachers may feel uncertain about how to deal with these cases, as they might feel responsible to take action to prevent further harm. This study aims to explore how ethics teachers in medical schools would respond to a student report of unethical or unprofessional behaviour during the clinical training phase (clerkship) that is alarming and potentially harmful for patients or students themselves. METHODS: This study used qualitative methods with purposive sampling. We conducted in-depth interviews with 17 teachers from 10 medical schools in Indonesia. We asked if they had heard any alarming and harmful cases from students and provided two cases as examples. RESULTS: Four teachers shared their own cases, which they perceived as disturbing and alarming. The cases included power abuse, fraud and deception, violation of patient's rights and autonomy, and sexual harassment. Regarding teachers' responses in general, we found three main themes: (1) being assertive, (2) being careful, (3) barriers and facilitators. Most teachers were convinced of the need to take action despite numerous barriers, which they identified, leading to doubts and concerns in taking action. Our study shows that formal education in ethics might not necessarily influence how teachers respond to alarming cases, and that their responses are mainly influenced by how they perceive their role and responsibility as teachers. CONCLUSIONS: Our study suggests that teachers should carefully consider the risks and consequences before taking action upon alarming cases to prevent further harm, and that support from higher authorities might be crucial, especially in the Indonesian context. Our study also shows that taking action as a group might be appropriate in certain cases, while personal approaches might be more appropriate in other cases. Most importantly, school leaders and administrators should develop effective organisational culture and support students and teachers for their ethical responsibility commitment.

A protocol study of participatory action research: integrated care pathway for pregnant women with heart disease in Indonesia.

BACKGROUND: Heart diseases are increasingly identified as an important indirect cause of maternal mortality in several cities in Indonesia. The management of pregnancy with heart diseases requires a multidisciplinary approach, and interprofessional collaboration practice (IPCP) is critical to improving the quality of patient care. To enable the effective implementation of IPCP, integrated care pathways (ICPs) are needed to define the roles and responsibilities of the health professionals involved. This study aims to examine the obstacles and enabling factors of IPCP, to develop and use ICPs in the implementation of IPCP in health care services for pregnant women with heart diseases. METHODS: A participatory action study consisting of four stages (diagnostic, planning, implementation, and evaluation) will take approximately 2 years after consensus of ICPs are made. The primary data collection process will employ consensus, observations, focus group discussions, and in-depth interviews throughout the four stages, while secondary data from referral documents and medical records will be collected mainly during the diagnostic and evaluation stages. The findings are being analysed and will then be used to develop an ICPs through consensus building at the planning stage to be applied in the implementation stage. Finally, the implementation outcome, including acceptability, adoption, appropriateness, and feasibility of IPCP, will be assessed in the evaluation stage. All qualitative data will be analysed thematically by two coders using NVIVO 12 software. DISCUSSION: This research aims to assess the needs of IPCP, develop and use the ICPs in the implementation of IPCP in health care services for pregnant women with heart diseases. Findings from this study will be used for health service planning and policy making to strengthen practice of IPCP during the referral process. As a result, pregnant women with heart disease will have better access to high-quality services at every health care facility to reduce maternal mortality.

The experience of family caregivers of patients with cancer in an Asian country: A grounded theory approach.

BACKGROUND: Strong family bonds are part of the Indonesian culture. Family members of patients with cancer are intensively involved in caring, also in hospitals. This is considered "normal": a societal and religious obligation. The values underpinning this might influence families' perception of it. AIM: To explore and model experiences of family caregivers of patients with cancer in Indonesia in performing caregiving tasks. DESIGN: A grounded theory approach was applied. The constant comparative method was used for data analysis and a paradigm scheme was employed for developing a theoretical model. SETTING/PARTICIPANTS: The study was conducted in three hospitals in Indonesia. The participants were family caregivers of patients with cancer. RESULTS: A total of 24 family caregivers participated. "Belief in caregiving" appeared to be the core phenomenon. This reflects the caregivers' conviction that providing care is an important value, which becomes the will power and source of their strength. It is a combination of spiritual and religious, value and motivation to care, and is influenced by contextual factors. It influences actions: coping mechanisms, sharing tasks, and making sacrifices. Social support influences the process of the core phenomenon and the actions of the caregivers. Both positive and negative experiences were identified. CONCLUSION: We developed a model of family caregivers' experiences from a country where caregiving is deeply rooted in religion and culture. The model might also be useful in other cultural contexts. Our model shows that the spiritual domain, not only for the patient but also for the family caregivers, should be structurally addressed by professional caregivers.

Hospitals accreditation status in Indonesia: associated with hospital characteristics, market competition intensity, and hospital performance?

BACKGROUND: Hospital accreditation is widely adopted as a visible measure of an organisation's quality and safety management standards compliance. There is still inconsistent evidence regarding the influence of hospital accreditation on hospital performance, with limited studies in developing countries. This study aims to explore the association of hospital characteristics and market competition with hospital accreditation status and to investigate whether accreditation status differentiate hospital performance. METHODS: East Java Province, with a total 346 hospitals was selected for this study. Hospital characteristics (size, specialty, ownership) and performance indicator (bed occupancy rate, turnover interval, average length of stay, gross mortality rate, and net mortality rate) were retrieved from national hospital database while hospital accreditation status were recorded based on hospital accreditation report. Market density, Herfindahl-Hirschman index (HHI), and hospitals relative size as competition indicators were calculated based on the provincial statistical report data. Logistic regression, Mann-Whitney U-test, and one sample t-test were used to analyse the data. RESULTS: A total of 217 (62.7%) hospitals were accredited. Hospital size and ownership were significantly associated with of accreditation status. When compared to government-owned, hospital managed by ministry of defense (B = 1.705, p = 0.012) has higher probability to be accredited. Though not statistically significant, accredited hospitals had higher utility and efficiency indicators, as well as higher mortality. CONCLUSIONS: Hospital with higher size and managed by government have higher probability to be accredited independent to its specialty and the intensity of market competition. Higher utility and mortality in accredited hospitals needs further investigation.

Comparison of the lived experiences of family caregivers of patients with dementia and of patients with cancer in Indonesia.

ABSTRACTBackground:Dementia, even more than cancer, demands long-term care. While in Indonesia cancer is accepted as a disease requiring caregiving, dementia is still considered "a normal condition." These differences might affect the experiences of caregivers, especially those relating to social health, the subject of our study. We aim to describe and compare the lived experiences of family caregivers of patients with cancer (PWC) with those of patients with dementia (PWD) in Yogyakarta, Indonesia, and to explore the role of their social health in these experiences. METHOD: A qualitative design was applied. In-depth face-to-face interviews were conducted with PWC and PWD caregivers in two outpatient clinics of a tertiary hospital. The constant comparative method was applied to analyze the data that were interpreted using the concept of social health to explore the experiences of the caregivers. We used Atlas.ti software. RESULTS: Three themes were identified: problems with caregiving, dealing with problems, and beliefs in caregiving. We found more similarities than differences in the experiences of caregivers in both groups. Half of the categories were related to social health: challenges, consequences, hiding, social support, and the caregiver's approach. The organization of dementia care is characterized by simplicity and direct ties between medical specialists, PWD, and caregivers, whereas cancer care encounters coordination problems. CONCLUSIONS: Family caregivers of both groups mostly had similar experiences of the caregiving process. Gaining a better understanding of the specific experiences of caregivers, and their social health, opens new avenues for interventions to improve their quality of life.

Designing and collecting data for a longitudinal study: the Sleman Health and Demographic Surveillance System (HDSS).

BACKGROUND: This paper describes the methodological considerations of developing an urban Health and Demographic Surveillance System (HDSS), in the Sleman District of Yogyakarta, Indonesia. METHODS: 1) The Sleman District was selected because it is mostly an urban area. 2) The minimum sample size was calculated to measure infant mortality as the key variable and resulted in a sample of 4942 households. A two-stage cluster sampling procedure with probability proportionate to size was applied; first, 216 Censuses Blocks (CBs) were selected, and second, 25 households in each CB were selected. 3) A baseline survey was started in 2015, and collected data on demographic and economic characteristics and verbal autopsy (VA); the 2nd cycle collected updated demographic data, VA, type of morbidity (communicable and non-communicable diseases, disability and injury) and health access. 4) The data were collected at a home visit through a Computer-Assisted Personal Interview (CAPI) on a tablet device, and the data were transferred to the server through the Internet. 5) The quality control consisted of spot-checks of 5% of interviews to control for adherence to the protocol, re-checks to ensure the validity of the interview, and computer-based data cleaning. 6) A utilization system was designed for policy-makers (government) and researchers. RESULTS: In total, 5147 households participated in the baseline assessment in 2015, and 4996 households participated in the second cycle in 2016 (97.0% response rate). CONCLUSIONS: Development of an urban HDSS is possible and is beneficial in providing data complementary to the existing demographic and health information system at local, national and global levels.

Maternal care quality in near miss and maternal mortality in an academic public tertiary hospital in Yogyakarta, Indonesia: a retrospective cohort study.

BACKGROUND: Reducing maternal mortality remains a major challenge for health care systems worldwide. The factors related to maternal mortality were extensively researched, and maternal death clusters around labour, delivery and the immediate postpartum period. Studies on the quality of maternal care in academic medical centre settings in low income countries are uncommon. METHODS: A retrospective cohort study of maternal deaths was conducted in an academic public tertiary hospital in Yogyakarta, and maternal near misses were used as controls. Data were obtained from medical records from February 1, 2011 to September 30, 2012. Three groups of variables were measured: (1) timeliness of care, (2) adherence to a standard of process indicators, and (3) associated extraneous variables. Variables were analysed using logistic regression to explore their effects on maternal mortality. RESULTS: The mean of triage response time and obstetric resident response time were longer in maternal deaths (8 ± 3.59 and 36.17 ± 23.48 min respectively) compared to near misses (1.29 ± 0.24 and 18.78 ± 4.85 min respectively). Near misses more frequently received oxytocin treatment than the maternal deaths (OR 0.13; 95%CI 0.02-0.77). Magnesium sulfate treatment in severe-preeclampsia or eclampsia was less given in maternal deaths although insignificant statistically (OR 0.19; 95% CI 0.03-1.47). Prophylactic antibiotic was also more frequently given in near misses than in maternal deaths though insignificant statistically (OR 0.3; 95% CI 0.06-1.56). Extraneous variables, such as caesarean sections were less performed in maternal deaths (OR 0.15; 95% CI 0.04-0.51), vaginal deliveries were more frequent in maternal deaths (OR 3.47; 95% CI 1.05-11.54), and more women in near misses were referred from other health care facilities (OR 0.09; 95% CI 0.01-0.91). CONCLUSIONS: The near misses had relatively received better quality of care compared to the maternal deaths. The near misses had received faster response time and better treatments. Timely referral systems enabled benefits to prevent maternal death.

Clinical Outcomes of Geriatric Care in Cipto Mangunkusumo Hospital, Before and After the Implementation of National Health Insurance Program.

BACKGROUND: the National Health Insurance (NIH/JKN) has been enacted since January 2014. Various outcomes of geriatric patient care, such as improved functional status and quality of life have not been evaluated. Prolonged hospitalization and re-hospitalization are potentially affecting the efficiency care of this vulnarable group. This study aimed to identify the differences of functional status improvement, quality of life improvement, length of stay, and hospitalization of geriatric patients admitted to CMH between prior to and after NHI implementation. METHODS: a cohort study with historical control was conducted among geriatric patients admitted to Acute Geriatric Ward CMH Hospital on two periods of time: January-December 2013 (pre-NHI implementation) and June 2014-May 2015 (after NHI implementation). Patients who died within 24 hours of hospital admission, those with APPACHE II score >24, advance stage cancer, transfer to other wards before they were discharged or have incomplete record were excluded from the study. Data on demographical and clinical characteristics, functional status, quality of life, length of stay, and re-hospitalization were taken from patient's medical record. The differences of studied outcomes were analyzed using t-test or Mann-Whitney test. RESULTS: there were 102 subjects in pre-NHI and 135 subjects in NHI groups included in the study. Median lengths of stay were not different between two groups (12.5 days in pre-NHI and 10 days in NHI groups, p=0.087), although the proportion of patients with in-hospital stay less than 14 days was higher in NHI group. The difference of functional status of discharged patients in pre-NHI and NHI groups were 3 and 3 (p=0.149) respectively, whereas for health-related quality of life, although NHI group in the beginning showed a lower quality of life compared to the pre-NHI (0.163 [0.480] vs. 0.243 [0.550]; p=0.012). However, after incorporating comprehensive geriatric assessment (CGA) the quality of life improved significantly by the end of in-hospital care in both groups. Re-hospitalization incidence in NHI group was lower compared to pre-NHI (7 [5.2%] vs. 13 [12.7%]; p=0.038). CONCLUSION: our study shows that there was  no  significant difference regarding length of stay, functional status, and health-related quality of life between prior to and after national health insurance implementation on admitted geriatric patients. Rehospitalization incidence showed better results in NHI group and hence NHI implementation is favored.

A mixed-method analysis of provider adherence to integrated antenatal care guideline in BEmONC and Non BEmONC primary health center: An Indonesian case.

Provider adherence to the integrated antenatal care (ANC) procedure is an important indicator of high-quality ANC. The procedure is intended to avoid missed opportunities to detect the risk of abnormalities in pregnancy. This study aims to assess the provider's adherence to integrated ANC in Basic Emergency Obstetric and Newborn Care (BEmONC) and non-BEmONC Primary Health Center (PHC). This study employed an explanatory sequential mixed-method design. The quantitative phase reviewed 149 medical records of pregnant women in the four PHCs in Semarang from January until February 2020. The findings were used to describe the provider's adherence to the integrated ANC and lead to the contributing factors which should be explored in the qualitative phase. The study involved four in-depth interviews with midwife coordinators in four PHCs. The Mann-Whitney and Chi-square test was employed to analyse the quantitative data, while the thematic analysis was undertaken on the qualitative data. The provider's adherence to the guideline did not differ between BEmONC and non-BEmONC PHC. The general physical examination of the patients (18.81%) and dentist visits (84.6%) were not done in either BEmONC or non-BEmONC PHC. Incomplete laboratory tests were haemoglobin (28.2%) and urine protein (38.9%). The barriers to adherence to the integrated ANC guideline were related to an imbalance of resources, role and responsibility issues among doctors and midwives, and policy issues. This study found low BEmONC nor non-BEmONC PHC adherence to the integrated ANC guideline. A Periodic evaluation of the implementation of integrated ANC to ensure its high-quality implementation in Indonesia is needed.

Reanalysis of cluster randomised trial data to account for exposure misclassification using a per-protocol and complier-restricted approach.

The intention-to-treat (ITT) analysis of the Applying Wolbachia to Eliminate Dengue (AWED) trial estimated a protective efficacy of 77.1% for participants resident in areas randomised to receive releases of wMel-infected Aedes aegypti mosquitoes, an emerging dengue preventive intervention. The limiting assumptions of ITT analyses in cluster randomised trials and the mobility of mosquitoes and humans across cluster boundaries indicate the primary analysis is likely to underestimate the full public health benefit. Using spatiotemporally-resolved data on the distribution of Wolbachia mosquitoes and on the mobility of AWED participants (n = 6306), we perform complier-restricted and per-protocol re-examinations of the efficacy of the Wolbachia intervention. Increased intervention efficacy was estimated in all analyses by the refined exposure measures. The complier-restricted analysis returned an estimated efficacy of 80.7% (95% CI 65.9, 89.0) and the per-protocol analysis estimated 82.7% (71.7, 88.4) efficacy when comparing participants with an estimated wMel exposure of ≥ 80% compared to those with <20%. These reanalyses demonstrate how human and mosquito movement can lead to underestimation of intervention effects in trials of vector interventions and indicate that the protective efficacy of Wolbachia is even higher than reported in the primary trial results.

Predicting the dengue cluster outbreak dynamics in Yogyakarta, Indonesia: a modelling study.

Background: Human mobility and climate conditions are recognised key drivers of dengue transmission, but their combined and individual role in the local spatiotemporal clustering of dengue cases is not well understood. This study investigated the effects of human mobility and weather conditions on dengue risk in an urban area in Yogyakarta, Indonesia. Methods: We established a Bayesian spatiotemporal model for neighbourhood outbreak prediction and evaluated the performances of two different approaches for constructing an adjacency matrix: one based on geographical proximity and the other based on human mobility patterns. We used population, weather conditions, and past dengue cases as predictors using a flexible distributed lag approach. The human mobility data were estimated based on proxies from social media. Unseen data from February 2017 to January 2020 were used to estimate the one-month ahead prediction accuracy of the model. Findings: When human mobility proxies were included in the spatial covariance structure, the model fit improved in terms of the log score (from 1.748 to 1.561) and the mean absolute error (from 0.676 to 0.522) based on the validation data. Additionally, showed only few observations outside the credible interval of predictions (1.48%) and weather conditions were not found to contribute additionally to the clustering of cases at this scale. Interpretation: The study shows that it is possible to make highly accurate predictions of the within-city cluster dynamics of dengue using mobility proxies from social media combined with disease surveillance data. These insights are important for proactive and timely outbreak management of dengue.

Utility of surveillance data for planning for dengue elimination in Yogyakarta, Indonesia: a scenario-tree modelling approach.

INTRODUCTION: Field trials and modelling studies suggest that elimination of dengue transmission may be possible through widespread release of Aedes aegypti mosquitoes infected with the insect bacterium Wolbachia pipientis (wMel strain), in conjunction with routine dengue control activities. This study aimed to develop a modelling framework to guide planning for the potential elimination of locally acquired dengue in Yogyakarta, a city of almost 400 000 people in Java, Indonesia. METHODS: A scenario-tree modelling approach was used to estimate the sensitivity of the dengue surveillance system (including routine hospital-based reporting and primary-care-based enhanced surveillance), and time required to demonstrate elimination of locally acquired dengue in Yogyakarta city, assuming the detected incidence of dengue decreases to zero in the future. Age and gender were included as risk factors for dengue, and detection nodes included the probability of seeking care, probability of sample collection and testing, diagnostic test sensitivity and probability of case notification. Parameter distributions were derived from health system data or estimated by expert opinion. Alternative simulations were defined based on changes to key parameter values, separately and in combination. RESULTS: For the default simulation, median surveillance system sensitivity was 0.131 (95% PI 0.111 to 0.152) per month. Median confidence in dengue elimination reached 80% after a minimum of 13 months of zero detected dengue cases and 90% confidence after 25 months, across different scenarios. The alternative simulations investigated produced relatively small changes in median system sensitivity and time to elimination. CONCLUSION: This study suggests that with a combination of hospital-based surveillance and enhanced clinic-based surveillance for dengue, an acceptable level of confidence (80% probability) in the elimination of locally acquired dengue can be reached within 2 years. Increasing the surveillance system sensitivity could shorten the time to first ascertainment of elimination of dengue and increase the level of confidence in elimination.

Impact of randomised wmel Wolbachia deployments on notified dengue cases and insecticide fogging for dengue control in Yogyakarta City.

BACKGROUND: Releases of Wolbachia (wMel)-infected Aedes aegypti mosquitoes significantly reduced the incidence of virologically confirmed dengue in a previous cluster randomised trial in Yogyakarta City, Indonesia. Following the trial, wMel releases were extended to the untreated control areas, to achieve city-wide coverage of Wolbachia. OBJECTIVE: In this predefined analysis, we evaluated the impact of the wMel deployments in Yogyakarta on dengue hemorrhagic fever (DHF) case notifications and on the frequency of perifocal insecticide spraying by public health teams. METHODS: Monthly counts of DHF cases notified to the Yogyakarta District Health Office between January 2006 and May 2022 were modelled as a function of time-varying local wMel treatment status (fully- and partially-treated vs untreated, and by quintile of wMel prevalence). The frequency of insecticide fogging in wMel-treated and untreated areas was analysed using negative binomial regression. RESULTS: Notified DHF incidence was 83% lower in fully treated vs untreated periods (IRR 0.17 [95% CI 0.14, 0.20]), and 78% lower in areas with 80-100% wMel prevalence compared to areas with 0-20% wMel (IRR 0.23 [0.17, 0.30]). A similar intervention effect was observed at 60-80% wMel prevalence as at 80-100% prevalence (76% vs 78% efficacy, respectively). Pre-intervention, insecticide fogging occurred at similar frequencies in areas later randomised to wMel-treated and untreated arms of the trial. After wMel deployment, fogging occurred significantly less frequently in treated areas (IRR 0.17 [0.10, 0.30]). CONCLUSIONS: Deployments of wMel-infected Aedes aegypti mosquitoes resulted in an 83% reduction in the application of perifocal insecticide spraying, consistent with lower dengue case notifications in wMel-treated areas. These results show that the Wolbachia intervention effect demonstrated previously in a cluster randomised trial was also measurable from routine surveillance data.

Dutch and Indonesian teachers on teaching medical ethics: what are the learning goals?

Previous literature has discussed the different views, the diverse goals and scope of ethics education, and the need for a more homogenous curriculum in medical ethics. Since ethics is about values, and values are partly influenced by culture, we question to what extent teachers' perceptions concerning learning goals of medical ethics curricula are similar or different in two different countries, and if differences in learning goals are acceptable or problematic. We conducted in-depth interviews with 36 medical ethics teachers, 20 from Indonesia and 16 from the Netherlands, and explored what they think are the important learning goals. We found three similar goals, with slightly different perceptions, between the two groups: (1) being professional, (2) dealing with ethical problems, and (3) being part of society. We also found four other goals that differed between the two countries: (4) understanding one-self and (5) learning from others from the Netherlands; (6) being faithful/pious and (7) obeying rules/standards from Indonesia. We suggest that despite similar goals shared globally, there might be differences in how teachers in different cultural contexts perceive the goals with their local values and translate them into the curricula. Differences in learning goals are common and natural, often reflected by historical and sociocultural contexts, and should not become a barrier for teachers in different regions to collaborate. Understanding these differences may be an important goal for teachers themselves to broaden their knowledge and perspectives.

Implementation fidelity of tuberculosis preventive therapy for under five children exposed to sputum smear positive pulmonary tuberculosis in Kaski district, Nepal: An implementation research.

INTRODUCTION: In line with the WHO recommendation, Nepal has started implementing Tuberculosis prevention therapy (TBPT) for under five children exposed to Sputum Smear Positive Pulmonary Tuberculosis, as one of the strategies for prevention, care and control of TB. Implementation fidelity study is important to assess on what extent preventive program is being implemented. The objective of the study measured the implementation fidelity of TBPT program Kaski district, Nepal. METHODS: We used a mixed-method explanatory sequential design study. Quantitative data were collected through retrospective review of records from April 2018 to May 2019 and level of adherence was established. Moderating factors influencing the implementation of TBPT were TBPT were assessed qualitatively. Sixteen in-depth interviews and a focus group discussion was conducted purposively with responsible stakeholders. The study was guided by the Conceptual Framework for Implementation Fidelity (CFIR) developed by Carroll. RESULTS: The majority of the components of the TBPT program were found to be implemented with a moderate level of fidelity. The proportion of under five years children initiate and complete the full course of TBPT was 72.5% and 75.86% respectively. The proportion of index cases traced for household contact, contact tracing within two months and timely initiation of therapy within two months were 54.19%, 82.73% and 86.20%. Moderating factors identified in the implementation of the program were contact tracing and enrollment, partnership and ownership, training resources, medication, awareness and information dissemination. CONCLUSION: The TBPT program is being moderately implemented in Kaski districts. Addressing the key challenges identified in contact tracing, partnership/ownership, incentives, training and knowledge of health workers results in more identification of children eligible for TBPT.

Disruption of spatiotemporal clustering in dengue cases by wMel Wolbachia in Yogyakarta, Indonesia.

Dengue exhibits focal clustering in households and neighborhoods, driven by local mosquito population dynamics, human population immunity, and fine scale human and mosquito movement. We tested the hypothesis that spatiotemporal clustering of homotypic dengue cases is disrupted by introduction of the arbovirus-blocking bacterium Wolbachia (wMel-strain) into the Aedes aegypti mosquito population. We analysed 318 serotyped and geolocated dengue cases (and 5921 test-negative controls) from a randomized controlled trial in Yogyakarta, Indonesia of wMel deployments. We find evidence of spatial clustering up to 300 m among the 265 dengue cases (3083 controls) in the untreated trial arm. Participant pairs enrolled within 30 days and 50 m had a 4.7-fold increase (compared to 95% CI on permutation-based null distribution: 0.1, 1.2) in the odds of being homotypic (i.e. potentially transmission-related) as compared to pairs occurring at any distance. In contrast, we find no evidence of spatiotemporal clustering among the 53 dengue cases (2838 controls) resident in the wMel-treated arm. Introgression of wMel Wolbachia into Aedes aegypti mosquito populations interrupts focal dengue virus transmission leading to reduced case incidence; the true intervention effect may be greater than the 77% efficacy measured in the primary analysis of the Yogyakarta trial.

A Cost-Effectiveness Analysis of Pre-Exposure Prophylaxis to Avert Rabies Deaths in School-Aged Children in India.

Children contribute to one-half of the total painful rabies mortalities in India. The state-of-the-art rabies mortality averting strategies need exploration for the effective implementation of pre-exposure prophylaxis (PrEP) in India. This study reports on the economic evaluation of various PrEP and post-exposure prophylaxis (PEP) strategies to avert rabies mortalities in school-aged children in India. A decision tree model has been developed for children in the age group of 5-15 years to evaluate various PrEP + PEP and PEP only regimens. The 2-site intradermal regimen administered on day zero and seven was chosen as the intervention [PrEP (I)]. ICER was calculated from the quasi-societal and quasi-health systems' perspectives for the base case analysis, along with one-way sensitivity, and scenario analyses for each regimen. The incremental DALYs averted per million population with the implementation of PrEP (I) ranged between 451 and 85,069 in 2020. The ICER was reported in the range of USD 384-352/DALY averted (non-dominant) in comparison to PEP regimens from a quasi-societal perspective. PrEP (I) is reported to be 'very cost effective' in comparison with PEP regimens from the quasi-societal and quasi-health systems' perspectives and reduce deaths by up to 89.9%. This study concludes that the PrEP (I) regimen is a cost-effective and life-saving strategy to avert painful mortalities due to rabies in school-aged children in India.
